emergency running position are stored in the control module.
-
Adaptation step 3: The throttle valve is set to a value above emergency position.
-
Adaptation step 4: The output stage of the throttle valve actuator is switched off. Now, the mechanical spring must set the throttle valve to the
previously learned emergency position within a specified time (spring return test).
-
Adaptation step 5: The throttle valve is closed by the throttle valve actuator (under mechanical impact).
-
Adaptation step 6. The angle sensor values for lower mechanical impact are stored in the control module. Finally, the lower electrical impact is
derived from this (calculated) and stored in control module.
-
Adaptation step 7: The output stage of the throttle valve actuator is switched off at lower mechanical impact. Now the mechanical spring places the
throttle valve in emergency position (spring raising test).
-
Adaptation step 8: Angle sensor values are checked.
